【正文】 2021 屆畢業(yè)設(shè)計 原文 Commonly used grinding machine As a kind of important ultraprecision processing method， the advantage of grinding is high machining accuracy, processing materials range, almost suitable for all kinds of materials processing, grinding can get very high precision and shape accuracy, even can reach the limit, the machining accuracy of grinding device is simple, does not need a lot of the plex mechanical and not demanding equipment precision conditions. As a super finishing one method, grinding machine is mainly used for the high precision grinding workpiece plane, the surface of cylindrical workpieces both inside and outside, tapered face inside, sphere, thread face and other type surface. Its main types have disetype grinding machine, shaft type grinding machine, magic grinding machine and all kinds of special grinding machine. Disetype grinding machine points single plate and doubletray two to doubletray grinding machine used the most mon. In doubletray polishing machine, multiple workpiece and into the mill plate, located on the cage between inside, maintain frame and workpiece drives by eccentric or pla of plane parallel movement. The mill rotating, the parallel with the grinding plate can not turn, or with grinding plate under negative spin, and can move to pressure workpiece (pressure adjustable). In addition, with the grinding plate can also turning round pillar rocker to Angle, unloading workpieces. Doubletray grinding machine is mainly used for processing two parallel planes, a plane (two pressure should be increased to the workpiece accessorie), outside YuanZhuMian and sphere (with belt vshaped slot grinding plate), etc. YuanZhuMian, because the processing and workpiece to both sliding, shall be reasonable choose to keep rolling type and arrangement plane slots Angle. Only a single plate grinding machine, used for grinding plate under the grind workpiece under plane, can make the different shapes and sizes with plate processing, grinding workpiece higher precision. Some grinding machine with the grinding process can be automatic calibration grinding plate institution. Shaft type grinding machine from positive, negative spin of spindle drive workpiece or inquiry with adjustable grinding ring or abrasive (great) rotation, the structure is simple, used for grinding inside and outside cylindrical planes. Magic grinding machine is by using magic force transmission to 中國地質(zhì)大學(xué) 長城學(xué)院 2021 屆畢業(yè)設(shè)計 stainless steel mill for high frequency workpiece needle to rotary motion。 But for precision workpiece in the hole and blind Angle, tiny crack rise obvious good polishing grinding remove burr effect. Special grinding machine by grinding workpiece in accordance with the different, have central hole grinding machine, steel ball grinding machine and gear grinding machine, etc. In addition, still have a kind of adopting similar centerless grinding principle unconditio
